Abstract

The invention discloses a high-precision suction mold which comprises a mold body and a vacuum system, wherein the vacuum system comprises a vacuum pump, a negative pressure tank, a vacuum chamber and suction holes; the vacuum pump, the negative pressure tank, the vacuum chamber and the suction holes are communicated sequentially through a pipeline; a plurality of suction holes are uniformly distributed on a cavity surface in the mold body; the diameter of each suction hole ranges from 0.5 mm to 1.5 mm; and the mold body is made from gypsum, copper, aluminum or an aluminum alloy. According to the mold, the productivity and quality of workpieces can be improved, meanwhile, raw materials of plastic workpieces can be saved remarkably, energy can be saved, and the service life is long.

Description

technical field [0001] The invention relates to the field of molds, in particular to a high-precision plastic-absorbing mold. Background technique [0002] In modern production, plastic molds shape raw materials in a certain way with their specific shapes, and are important process equipment for mass production of various products and daily necessities. With the continuous improvement of the technical level and the continuous development of the social economy, people have higher and higher requirements for the variety, quantity, quality and style of industrial products, and the use of molds is becoming more and more extensive. The research and development of mold technology is of special significance for promoting the development of the national economy. [0003] With the continuous development of the plastic industry, higher and higher requirements are put forward for plastic molds. The existing plastic molds have insufficient precision and service life, so they cannot mee...
